Lloyd Dunlap wrote that he had replaced the plain steel bushings that the calipers slide on, with stainless steel.

Boy! Do I agree with that! The last time I replaced my pads, I noted that they were worn unevenly, in in a manner that indicated they were not being pressed flatly against the disk. On taking a closer look, it
was obvious that the bushings mentioned above by Lloyd were badly rusted (plain steel) with build-up of corrosion to the point that the
calipers just couldn't move freely and evenly. At that time, I took
the decision to just clean them up to bare metal and hot-dip them in wax, with a plan to replace them with stainless at the next re-pad. Not the best decision probably, but it was late, and I had planned to leave on my annual fishing trip in Idaho the next day and I didn't have the SS material. Now, the pads are worn only about 50% and close inspection reveals the calipers are canted, wearing the pads unevenly again. So it's time to follow thru and put in the stainless bushings.

My question Lloyd, what is the source of the material you used for
your new bushings? I know you said you installed what you thought was
300 series SS, but did you have to have them machined from stock, or
did you find some appropriately sized tubing? Are you content with your choice of alloy, i.e., how has it held up?

I'm definitely going to do this as well as replace the Nylaflow brake
lines - you all out there have scared me enough about that one - (I may be in the group that haven't yet had a problem with it, and I may also be in the group that some folks believe can't learn new tricks - but I ain't stupid - I sincerely hope!). So I'd like to gather all the materials ahead of time.
